坦桑尼亚Nzega绿岩带Matinje金矿勘查标志研究

摘要

The analysis research on the geological characters of Matinje Gold Deposit in Tanzania is favorable to layout reasonable and effective exploration projects in other mining area nearby. Geological measurement and analysis has been carried out from three aspects, including basic geology, geophysical and geochemical exploration. The tectonic shear zone and greenstone belt are the geological factors of the mine genesis, and strong magnetic anomaly is the key geophysical indicator.%对坦桑尼亚Matinje金矿的地质特征进行相关分析研究,有助于对其他周边矿区进行合理有效的勘探.从基础地质、物探和化探等方面的勘查标志出发对Matinje金矿进行了测量和分析,认为构造剪切带和绿岩带是决定该金矿成因的地质因素,局部正负伴生强磁异常是形成金矿的重要航磁标志.
